-/*
-   This plugin intercepts some of the binary handling functions to
-   store uploaded files (as is) into a dedicated directory.
-   Because the ewiki database abstraction layer was not designed to
-   hold large files (because it reads records in one chunk), you may need
-   to use this, else large files may break.
-
-   WARNING: this is actually a hack and not a database layer extension,
-   so it will only work with the ewiki.php script itself. The database
-   administration tools are not aware of this agreement and therefore
-   cannot (for example) backup the externally stored data files!
-   If you later choose to disable this extension, the uploaded (and thus
-   externally stored) files then cannot be accessed any longer, of course.
-
-   - You must load this plugin __before__ the main script, because the
-     binary stuff in ewiki.php always engages automatically.
-   - The store directory can be the same as for dbff (filenames differ).
-   - All the administration tools/ are not aware of this hack, so __you__
-     must take care, when it comes to creating backups.
